Comprehensive testing assures durability at temperatures as low as -196C, making it a trusted choice in extreme cold-weather operations.

Unmatched Versatility and Compliance

This valve is crafted to ASTM-approved grades and offers multiple configuration options, such as flanged (RF/RTJ) and butt-welded ends. Each unit undergoes API 598 leakage testing and can include additional functionalities like locking devices, limit switches, or by-pass arrangements for specialized requirements.

Third-Party Inspected and Certified

Quality assurance is a priority, with third-party inspections available to ensure every product meets the highest standards. The BS 6364 Swing Check Valve is suitable for distributors, exporters, manufacturers, and traders alike, and is widely used in India for a range of cryogenic and industrial applications.

FAQ's of BS 6364 Swing Check Valve:

Q: How does the BS 6364 Swing Check Valve work in cryogenic service?

A: The BS 6364 Swing Check Valve operates automatically, allowing flow in one direction while preventing reverse flow. Its design ensures tight sealing, even in cryogenic conditions, due to BS 6364-compliant construction and rigorous cryogenic testing.

Q: What testing and inspection processes are followed for these swing check valves?

A: Each valve undergoes cryogenic testing as per the BS 6364 standard and leakage assessment according to API 598. Third-party inspection services are also available on request to guarantee quality and performance in critical applications.

Q: When should I choose a metal-to-metal versus a soft seat for the valve?

A: A metal-to-metal seat is typically chosen for high-temperature or abrasive services, offering durability and longevity. A soft seat provides enhanced tightness and is recommended when bubble-tight sealing is required at lower pressures or for sensitive media.

Q: Where are BS 6364 Swing Check Valves commonly used?

A: These valves are extensively utilized in cryogenic services such as LNG facilities, and liquid nitrogen or oxygen systems. Their robust design and compliance with international standards make them suitable for a wide range of gas and liquid handling applications in industrial and energy sectors.

Q: What are the benefits of using valves with flanged or butt-welded end connections?

A: Flanged ends facilitate straightforward installation and removal, ideal for routine maintenance. Butt-welded ends, available upon request, offer a more permanent, leak-tight connection for high-pressure or high-purity applications.

Q: How can users enhance the functionality of this swing check valve?

A: Optional add-ons such as a locking device, limit switches, or a by-pass arrangement can be incorporated. These enhancements allow for greater control, improved monitoring capabilities, and adaptability to specific operational requirements.
